Factor XII and blood clots in sickle cell disease

Official title: Role of Factor XII in Thrombo-Inflammatory Complications of Sickle Cell Disease

Funded at Univ of North Carolina Chapel Hill · NIH-11393008 · Data updated 2026-11-12

A research project tests how Factor XII affects blood clotting and inflammation in people with sickle cell disease to understand how it contributes to painful crises, clots, and organ damage.

Who could benefit from this research

Could help

People with sickle cell disease who experience or are at risk for vaso-occlusive crises and venous thrombosis.

Less likely to help

Patients without sickle cell disease or without risk of clotting or VOC are unlikely to benefit.

What this research studies

This project studies the role of Factor XII in sickle cell disease and how it may influence clotting and inflammation in patients. The team previously found that FXII is more active in sickle cell patients and that blocking FXII can reduce clotting in mouse models. By combining laboratory studies with human samples, they aim to map how FXII drives vaso-occlusive crises and organ injury. Results could identify new ways to prevent dangerous clots and pain episodes without increasing bleeding risk. The work could pave the way for targeted therapies for people living with SCD.

Why it matters

Potential benefit: If successful, this research could lead to safer, targeted treatments to prevent clots and organ damage in sickle cell disease.

How similar studies have gone: Previous studies in SCD and FXII suggest a meaningful link between FXII activity and thromboinflammatory processes, with promising results in animal models.
